The Last of Us Part 1 freezes my Ryzen 9 9950X3D while compiling shaders. Is this a core affinity issue?

Watching that progress bar freeze at 99% for three straight minutes was pure torture. The Ryzen 9 9950X3D is a beast, but the game was dumping all the compilation stress onto just two physical cores, leaving the others idling while two cores hit 100%. It was a maddening waste of hardware. I tried cranking my virtual memory up to 64GB first, but that did absolutely nothing for the thread allocation, and the compile time remained ridiculously long. I eventually used a process manager to manually extend the affinity of the compilation process across all 3D V-Cache cores and killed the Windows Search Indexer to stop I/O interference. In Resource Monitor, the load shifted from a crazy 100% vs 5% split to a balanced 60-80% across the board, nearly doubling the speed. I did have one crash when I first forced the affinity, but dropping the priority from 'Realtime' to 'High' fixed it. Temps are now 62-71℃ with RAM usage around 18-22GB. The thread scheduling is finally balanced, and it's a relief.
